MoTeC Overview 9

• 2 Wheel Speed

Expander Inputs

Additionally one E888 expander may be connected to read from 8 K-type

thermocouples.

Internal Sensors

The SDL also includes internal sensors for G-Force Lateral, G-Force Vertical,

Battery Voltage and SDL Internal Temperature.

Sensors

Different types of sensors are available to suit different types of

measurements.

Sensors convert a physical measurement (e.g. Pressure) into an electrical

signal (e.g. Volts). Different types of sensors generate different types of

electrical signals. For example most temperature sensors convert the

temperature into a variable resistance signal which may be measured by the

SDL Temperature inputs, however most wheel speed sensors generate a

variable frequency signal which must be connected to either a Digital input or

a Speed input.

Calibration

Calibration is the process of converting the electrical value, e.g. Volts into a

number that represents the physical value, e.g. Temperature.

All inputs can be calibrated to suit the connected sensor.

The calibrations can be selected from a number of predefined calibrations

provided by MoTeC, or they can be entered by the user.

Analog Voltage Inputs

The 8 Analog Voltage inputs are normally used to measure the signals from

analog voltage type sensors, i.e. sensors with variable voltage outputs, such

as:

• Rotary or linear potentiometers

• Signal conditioned 3 wire pressure sensors

• Thermocouple amplifiers

• Accelerometers
